8 Move the deflection yoke forward until the entire raster is green.
Landing adjustment is easier if the yoke is moved all the way forward and then moved back
until the raster is completely green.
9
Using the Color Purity key, replace the green raster with red and then blue raster,
each time checking for proper landing adjustment (color purity of each).
10 If the landing is not correct in step 9, repeat steps 6 through 9 for the best
compromise.
11 If the landing is not correct in step 10, readjust purity magnets for best landing of
each color.
12 When the landing adjustment is complete, tighten the deflection yoke clamp screw
just enough to keep the yoke from moving. DO NOT over tighten or you might
damage the CRT.
